A RICS home survey helps you understand a property’s condition before buying. To use it properly, you also need to understand what the surveyor could see, what could not be inspected and which questions require a different specialist.
A report is not a promise that the house has no hidden problems. Its value comes from an informed assessment of accessible parts of the building, a clear explanation of significant findings and practical advice on what to do next.
Trust Surveyors’ home-buying services cover surveys for purchasers. The inspection scope should be agreed around the building and the level of detail required.
Outside the property: follow the weather and the structure
The external inspection considers accessible and visible features such as roof coverings, chimneys, rainwater goods, walls, windows and doors. The surveyor looks for evidence that may explain present defects or signal a need for repair or investigation.
For example, a stain below a gutter becomes more meaningful when considered alongside displaced gutter joints and dampness inside the same wall. A crack is assessed in its context, including position, pattern and the surrounding construction. Neither observation should be turned into a diagnosis based on appearance alone.
The inspection is constrained by viewpoints and safe access. High or obscured roof areas may not be visible in full. Underground foundations are not normally exposed. A surveyor may comment on evidence of movement without having inspected the foundations themselves.
Inside: condition, connections and warning signs
Accessible internal areas can reveal damaged plaster, staining, unevenness, signs of timber deterioration or indications of previous alterations. The surveyor considers whether observations fit together. A newly decorated surface, for example, may restrict what can be inferred about an earlier leak.
Visible findings are recorded with the limitations that affect them. Furniture, stored belongings, floor coverings and fitted units can conceal areas. An inspection does not normally involve dismantling the seller’s home or carrying out destructive tests.
RICS publishes the Level 2 service and reporting description, which explains the relationship between inspection findings, access restrictions and condition ratings.
Roof spaces, floors and drainage
A loft inspection depends on the available hatch, safe access and the conditions inside. A full storage floor or tightly packed belongings can conceal timber and other areas. An inaccessible roof void remains a limitation, even when the rooms below appear sound.
At Level 3, the surveyor follows evidence further where it is safe and reasonable, with more detailed inspection of accessible elements. That does not mean every floorboard is lifted or every pipe is traced. Fixed finishes, physical access and permission still determine what can be examined.
The RICS Level 3 scope of inspection sets out the distinctions, including how accessible drainage chambers and normal drainage operation may be considered.
If drainage condition is important to the purchase, ask whether a separate drainage investigation is recommended. A visible inspection is not the same as a complete camera survey of underground runs.
Services: observation is not a safety certificate
A survey may describe the visible parts of heating, electrical, gas, water and drainage installations and identify concerns. It does not replace a qualified contractor’s specialist testing or certify that an installation complies with every relevant requirement.
A boiler producing warmth during a visit does not establish its servicing history or internal condition. An electrical consumer unit that looks recent does not establish the condition of concealed wiring. Missing records and visible warning signs need to be considered together.
Keep survey recommendations separate from the seller’s paperwork. A certificate may be relevant evidence, but its date, property address and scope still need checking. Ask the appropriate professional if the report identifies a gap that matters before purchase.
How to read the condition ratings
Where the report uses the RICS rating system, a rating 3 identifies a serious defect and/or a need for urgent repair, replacement or investigation. It is not permission to defer the issue for a year. A rating 2 indicates a defect needing repair or replacement without the same serious or urgent character. A rating 1 still assumes normal maintenance.
“Not inspected” is different from a satisfactory finding. Read the explanation of the restriction and its implications. The accompanying text should guide your decision; counting coloured boxes alone can obscure the most important issue.
A problem in one element may also explain a finding elsewhere. Keep the report’s photographs, descriptions and recommendations together when asking follow-up questions.
Build a useful list of follow-up questions
Instead of asking only whether the house is “good” or “bad”, write down the decisions the report leaves open:
- Which concerns should be investigated before legal commitment?
- What type of specialist is needed, and what should they be asked to examine?
- Does an inaccessible area materially affect confidence in the assessment?
- Which repair recommendations need contractor quotations?
- Which matters should go to the conveyancer rather than a builder?
For buyers who are still choosing the service, Trust’s survey and valuation overview explains the available starting points. Keep the original purpose clear: a condition survey, market valuation and legal investigation answer different questions.
Prepare access without hiding the evidence
Ask the estate agent or seller to arrange normal access to rooms, outbuildings and available hatches. Useful documents include records of alterations, known defects and relevant certificates. Do not ask anyone to force a hatch, move unsafe materials or open up construction without an agreed plan.
If you already have a concern, send it to the surveyor before the appointment. A dated photograph of staining and a description of when it appeared may help explain something that is dry on the inspection day.
Frequently asked questions
Are the foundations inspected directly?
Not normally. Home surveys are not excavation works. Evidence suggesting foundation or movement concerns can lead to recommendations for further investigation.
Will the survey test the electrics?
No. A home survey does not provide electrical installation testing. The report can identify visible concerns and recommend an appropriate electrical inspection.
Does a clear report guarantee no damp?
No. Conditions can vary with weather and occupation, and some areas may be concealed. Read the inspection limitations and advice about any suspicious signs.
Can the surveyor move everything to inspect behind it?
No. The agreed survey level and safe access govern what is moved or examined. Heavy furniture, fitted coverings and inaccessible voids can limit the inspection.
Does the survey check planning permissions?
It may identify alterations or issues requiring legal enquiries. Your conveyancer investigates approvals and other legal documentation; the survey does not replace that work.
Discuss the property with Trust Surveyors so the service can be scoped around your purchase, access arrangements and particular concerns.
